Abstract
A carabiner gate for a carabiner having an outer cylinder and an inner cylinder, that can only be opened with the use of a properly located magnet to move a sliding pin and allow rotation of the outer cylinder to open the carabiner.
Claims20
A magnetic gate for a carabiner having a closed position and an open position, comprising:
- an outer cylinder having a sliding pin recess internally disposed into an inside surface of said outer cylinder;
- an inner cylinder having a bore;
- said outer cylinder rotatably disposed outside of said inner cylinder;
- said bore containing a sliding pin;
- and
- a biasing means to bias said sliding pin towards said sliding pin recess in the closed position;
- wherein said sliding pin recess does not extend through to an outside surface of said outer cylinder.

A magnetic gate for a carabiner having a closed position and an open position, comprising:
- an outer cylinder having a sliding pin recess disposed on an inside surface of said outer cylinder and a sliding pin location structure on an outside surface of said outer cylinder;
- an inner cylinder disposed within said outer cylinder;
- said inner cylinder having a bore extending partially therethrough;
- a sliding pin made of ferrous material slidably disposed in said bore;
- said sliding pin having a shoulder;
- a sliding pin spring disposed within said bore;
- said sliding pin spring contacts said sliding pin to bias said sliding pin in said sliding pin recess in the closed position;
- and
- whereby when a magnet is placed near said sliding pin locating structure having a stronger force than the sliding pin spring, said sliding pin is displaced toward said sliding pin locating structure and removed from said sliding pin recess.
